Lightning Round: Perfect stock for young investors

It's that time again! Jim Cramer rang the lightning round bell, which means he gave his take on caller favorite stocks at rapid speed:

Box Inc: "I guess people just wanted to make money now, which it cannot do...But where were the insider sellers that everyone was so worried about? I didn't see them. I like it, but it's a tough market for tech."

Exelixis Inc: "I've liked that...EXEL came out to be one of my favorite biotechs, even up here at $6."

Taser International Inc: "I think that a young investor might be the key, because it is speculative but it is down a lot and I like the core business."

Public Storage: "Boy that group has just been so tough. This one has moved up 10 percent, I cannot endorse it up here. Even though I like it, there is other fish to fry. Have you looked at Ventas lately?"

Bristol-Myers Squibb: "You're thinking about selling Bristol-Myers? That would be wrong! I am a buyer of BMY."
